ably, in the construction hereinafter described which may be varied without de-V parting 'from the spirit of-my invention.

Referring to the drawings, similar numerals of reference indicate corresponding parts in the different views, in which 1 is the incasement, which in this case forms the main or supporting frame, and 2 is a covering for the same. Forthc purpose of :Eurnishing automatic lubrication for certain parts, the incasement o'r main-frame is made to form a reservoir or containerl 3, for holding a supply of oil, of which 4 indicates its eve To simplify the incasement or mainframe, supports 5 are made separately and secured thereto, as by bolts 6, and to prevent oil from escaping through these bolt holes the surface around them is raised and ribs 7 extend therefrom to furnish a better foundation for the supports. The surface around the holes in the base of the supports is also raised to prevent oil from escaping from in'casement, as by bosses 8.

t being desirable to retain and return the surplus oil from the journal bearings to the reservoir, it is necessary to avoid openings through which the oil might escape, the

heads of bolts are anchored in grooves 10, and to give free access to the reservoir, channels 11 beneath the bearings are provided.

Journaled in the main-frame is the Windwheel or' driving shaft 12, to which are rigidly secured gear-pinions 13. These 'pinionsmesh with and drive gear-wheels 14, said gear-wheels, in the present case, are preferably mounted upon stud-shafts 15. These stud-shafts are provided with heads 15 to retain said gears in lace, and are rigidly held by and extend rom4 boxes or anchors 16, said boxes 'or anchors being provided with downward projections 17, which projections fit into cavities or depressions in the main-frame, the object being Ito provide means for adjusting the studshats to alignment, and furnish rigid anchorage for them without perforating the walls of the incasement, thereby preventing escapcmcnt of the lubricant. i

For lubricating the bearings of shaft 12, each of thel gear-Wheels is provided with a bucket or lippe-r 18 with an opening or spill-way 19. so that as the gears revolve these buckets will elevate oil from the reservoir and in passing spill it into runways 'the wind-wheel shaft consumes a nals of shaft 12. This means oflubricationwas covered in a former application that terminated in United States Letters Patent No. 1,246,008. To lubricate the stud-shafts,

on which the gear-wheelsare mounted, each of the latter is provided with a bucket or dipper 23 that elevates oil from the reservoir, which is then conveyed via run-ways or channels 24 formed in connection with the web or along one of the arms, as the case may be, of the gear-Wheels to their hub and through holes 25 to the stud-shafts thereby lubricating the same.

This construction may be varied as it is quite apparent that oil may be elevated and conveyed to the stud-shafts by other means than those described! The friction caused by the end thrust of great deal of power, and to reduce this friction the application ofv an end thrust bearing has been devised, in which the regular cup 26, cone 27 and balls 28 may be used in connection with a dish or convex shaped part 29 to compensate for unevenness of resisting surface 30 to permit adjustment and a more uniform pressure on the balls. In application of this end-thrust bearing, in the -present case, the end of shaft 12 is reduced,

which forms a shoulder 31, which end passes through the appertures in the cupy and'cone, and if need be through the apperture 32 in the dish or convex shaped part, with the shoulder 31 resting against the bearing. This bearing is automatically lubricated in connection with the bearing of the windwheel shaft, and it is quite apparent that its construction may be varied without departing from the general principles or application of the device. A

Mounted in supports 5 is a shaft 33, which may be secured in any suitable manner, and upon this -shaft is pivotally mounted a frame or member 34. The hub 34' of this frame is provided with hoppers or receptacles 35, 35 which are separated by a partition 36. These receptacles are connected by openings 37, 37 with chambers 38, 38', which chambers are separated by a partition 36'. The object of these partitions is to prevent too much oil running to one Side of the pivoted frame and to assure a more even distribution to the different bearings. Chambers 38, 38 extend along the shaft and are connected with chambers 39, 39', or if desired, chambers 38, 38' may be omitted and the receptacles connected with chambers 39, 39 through openings 40, 40'. These latter chambers extend along the sides of -the pivoted frame, which sides are rigidly connected at their free, or opposite end from the hub, by s. connection 41. Near the free end of this pivoted frame a shaft 42 is pivotally mounted in hubs or bearings 43, 43', which shaft is rigidly secured to hub 44, of pitman 45, as' by pin 46. The other end of the pitman being pivotally mounted upon a Wrist-pin 47 that extends across and forms an Operating connection with the gearwheels 14 and is operated thereby. As this Wrist-pin and connections. dgring operation, becomes submerged in oil in the reservoir they require no further arrangement for lubrication. Each end of the hub 44 (see Figs. 6 and 7) has an extension from its lower part with a receptacle 4S, 48 therein to receive the overfiow of oil-from bearings 43, 43', and holes or channels 49, 49 from said receptacles to a partition midway of the hub and openings 50, 50' therefrom to channels 51, 51 formed on the pitman 45, through which the surplus oil is returned to the reservoir. The inner hubs of bearings 43, 43' are provided with downwardly extending lips or segments 52 (see Fig. 10) that enter receptacles 48, 48 to assure that the overflow of lubricant from said bearings enters said receptacles. lf freer outlet from bearings 43, 43 is desired, it may be'secured, as by holes 53, 53'. The objet of chambers in hub 44 is to reduce amount of Work in reaming to fit the shaft, and particularly in making casting to permit connecting the core of this hole with those for channels 48, 48 and openings 50, 50'. Also, near the free end of the pivoted frame, a shaft 54 is pivotally mounted in hubs or bearings 55, 55', which shaft is firmly secured to the hub 56 of the pump-rod head, as by pin 57, and near each endiof said hub a lip or segment 58, 58' extends downward so as to prevent surplus oil or drippings from said bearings being carried toward the pump-rod 56 and es.aping 'throu .ht-lie tubular mast 59. An upwardly Aexten lng tubular form 60, with an opening61 therein, through which the pump-rod may beoperated is provided within the incasement. This form is preferably integral with the incasement as it is essential it be so constructed as to prevent oil from escaping therefrom and it is necessary it be in line with the mast through which the pump-rod reciprocates. To reduce the chances of oil dripping through it and of dust entering the'incasement the opening `should be as small as the changing position of the pumprod will permit, and` to further avoid these contingencies a shutter 62 is provided (see Figs. 11 and 12), which is pivotally secured to said form, as by screws 63. This shut ter should be so supported as to permitfre'e movement that it may readily respond to the changing position of the pump-rod, To

It is obvious that other means than the shutter ma be employed, the object being to reduce t e escape of oil from or entrance of dust into the incasement. consequently, other means that will obtain that result may be adopted..

The incasement is provided with an extension or enlargement 1 in which bracket 65 is secured thereto, in any suitable manner, as by bolt 66, which bolt should be placed high enough to prevent oil from esca ing through the bolt hole. Supported by this bracket is a sprocket-wheel 67, upon which is mounted an endless chain or elevator 68 to which buckets or dippers are attached in any suitable manner.

In the upper end of supports 5 and above shaft 33 is rigidly mounted shaft 69,. which may be secured in any suitable manner, and onthis latter shaft is revolubly mounted a sprocket-wheel 70, which supports and transmits motion to the elevator. Extending 11pward from hub 34 and within receptacle 35 is a projection 71 to which may be secured, or an integral part thereof, is a segment gear 72. and mating with this gear is a segment gear 73, which is secured to or an integralpart of the hub 74. that forms a part of the clutch 75. This hub is provided with a run-way or channel 76 (see Figs. 2, 3 and 4), which extends close enough to the elevator to receive a supply of oil and con` veys it to opening 77 and through it to chamber 7 8 and opening 79 to the' segment gears thereby furnishingr lubrication to the different parts. The other part of this clutch is formed integral with one hub of the sprocket-wheel. Athe two halves of this clutch being held in working connection by an expansion spring 80, the latter .finding lodgement against one of the supports 5. To prevent backward movement of the sprocket-wheel and Aelevator when. the hub 74 is rocked rearwardl \v thereby releasinof the clutch 75. another clutch 81 is provided with teeth set in opposite direction to those of clutch and to prevent hub 82. which forms a part of' clutch 81 from rotating on the shaft. it is provided with a slotr 83 which is adapted to slide upon a stationary pin S3'. The teeth of this clutch are held in working connection by expansion spring which also finds lodgement against one of the supports 5. In operation, as the pivoted frame 34 is oscillated it imparts a similar movement to the segment gears which causes the hub 74 to be rocked on its shaft and through the clutch 75 imparts an intermittent forward movement to the sprocketwheel and to the elevator as the pivoted frame is raised. and as the frame is lowered the clutch teeth releases and moves back until they are again thrown into working connection by the action of the spring. Wvhile this clutch is backing up, the sprocket-wheel and elevator is held in: advanced position.

by clutch 81. To prevent chain of the elevator as it leaves the sprocket-wheel dragging on the rim of the receptacles a roller is provided.

A modification of the operating connection between the pivoted frame and the hub 74is shown in-Figs. 13 and 14, inl which the upward projection 71- is provided with a cam 84 in operative connection with a pin or projection 85 that extends from the hub 74. This hub has a run-way or channel 80 extendingr from near the elevator. where it receives oil and conveys it to a point over the operating connection to lubricate the same. Otherwise. the construction and op eration the same as previously dcscribmir Another modification ofthe operating connection between the pivoted frame and the hub 74 is shown inl Fig. 15. in which a lever 86 extends from said hub and is connected at its outer end with the pivoted frame, as by rod 8i'. In this construction as the pivoted frame is oscillate-d said lever moves in unison therewith. causing the hub- 74 to be rocked and operate connectingr parts as previously described.

It is apparent that various other modifications and arrangements may be made whereby oil can be elevated from the reset# voirto hub 34' or to the receptacles cminected therewith. To lubricate parts with oil from the elevator the buckets or dippers are so arranged that as they pass over the upper sprockebwhecl a part of the oil is delivered at each side. that is. bucket 88 has an openingSS' in its right forward corner. bucket an opening 89 in its left forward corner. and bucket 90 openings 90 at both forward corners, with a partition 91 for dividing the oil. The number of buckets may be increased or decreased as required to furnish'the requisite amount of lubricant and if only one bucket is used the construction shown in bucket 90 will dis` tribute to both sides. The oil thus delivered will lubricate the clutches. sprocket-wheel shaft. operating connections and other working parts, the surplus passing into receptacles 35, 35 and from them either through openings 37. 37' and chambers 38. 38. or through openings JJ). 1U to chambers 39. 39' and through the iattcr to shaft 54 and bearings 55. 55', over and partly around the former to shaft 42 and bearings 43. 43. lu` bricating the different bearings. the surplus passing from the last mentioned bearings to receptacles 18, 48 ,and from them through channels 49. 49 and openings 50, 50' to channels 51, 51 through which it is returned to the reservoir. The distribution being done `by gravit)v after thc ylubricant leaves the buckets of the elevator.

However, it is not the intention to limit the means for elevating and distributing lu- HYD br' ant to those described as it is evident the; other means may readily be employed for such purposes.
